Epidemics

The term &quote;epidemic&quote; is used to describe the spread of a disease or condition to a large number of people. The word &quote;epidemic&quote; is derived from the Greek word &quote;epi&quote;, meaning &quote;upon&quote;, and &quote;demos&quote;, meaning &quote;people&quote;. Hippocrates, a Greek physician who lived in the fourth century BC, was one of the first to use the term &quote;epidemic&quote;. He used it to describe the spread of disease through a population.
